The IP address of the next hop router for routes that have this set of
attributes.
The cost of the routes that have this set of attributes.
The source of the route information. The origin can be one of the
following:
• EGP – The routes with this set of attributes came to BGP through
EGP.
• IGP – The routes with this set of attributes came to BGP through
IGP.
• INCOMPLETE – The routes came from an origin other than one
of the above. For example, they may have been redistributed
from OSPF or RIP.
When BGP4 compares multiple routes to a destination to select the
best route, IGP is preferred over EGP and both are preferred over
INCOMPLETE.
The originator of the route in a route reflector environment.
The route-reflector clusters through which this set of attributes has
passed.
Aggregator information:
• AS Number shows the AS in which the network information in the
attribute set was aggregated. This value applies only to
aggregated routes and is otherwise 0.
• Router-ID shows the router that originated this aggregator.
Whether the network information in this set of attributes has been
aggregated and this aggregation has resulted in information loss.
• TRUE – Indicates information loss has occurred
• FALSE – Indicates no information loss has occurred
Note: Information loss under these circumstances is a normal part of
BGP4 and does not indicate an error.
The degree of preference for routes that use this set of attributes
relative to other routes in the local AS.
The communities that routes with this set of attributes are in.
The ASs through which routes with this set of attributes have passed.
The local AS is shown in parentheses.
